KT-20R克特磁性开关生产厂家,可替换进口品牌的磁性开关，如SMC,FESTO的圆形缸、米型缸和拉杆缸。
克特磁性开关配套气缸、油压缸使用，使用感磁传感器时，尽量远离强磁场或周围有导磁金属环境，避免干扰!
磁性感应开关，一般都是和磁性气缸配合使用的，一般磁性开关的工作电压为DC6-24V，具体的电压值可向提供产品的商家或厂家咨询。磁性开关的两根引线应根据其颜色来连接，如两根引线的颜色均为同色，说明其内部为干簧继电器型式，接线没有极性要求，一根线接正电源，另一根则可接至控制系统。如果两根引线的颜色分别为红色和黑色，说明其内部为霍尔式开关型式，则红线接正电源，而黑色线接至控制系统。一般磁性开关的电容量较小，仅100mA，故不宜用来直接驱动控制电磁阀，应先由磁性开关控制一只小继电器，再用继电器的触点去驱动控制电磁阀

KTGEE magnetic switch is used in conjunction with cylinders and hydraulic cylinders. When using magnetic sensors, try to stay away from strong magnetic fields or environments with magnetic conductive metals to avoid interference!
Magnetic induction switches are generally used in conjunction with magnetic cylinders. The working voltage of magnetic switches is usually DC6-24V. Specific voltage values can be consulted with the product supplier or manufacturer. The two leads of the magnetic switch should be connected according to their colors. If the colors of both leads are the same, it indicates that the internal structure is a dry spring relay type, and there is no polarity requirement for wiring. One wire is connected to the positive power supply, and the other wire can be connected to the control system. If the colors of the two leads are red and black respectively, it indicates that they are of Hall switch type inside. The red wire is connected to the positive power supply, while the black wire is connected to the control system. The capacitance of a general magnetic switch is relatively small, only 100mA, so it is not suitable for directly driving and controlling solenoid valves. Instead, a small relay should be controlled by the magnetic switch first, and then the contacts of the relay should be used to drive and control the solenoid valve
